Can anybody tell me the size of the WW fluid tubing?

Gents,

My truck had a non-Bullnose washer fluid reservoir in it and I just installed a correct reservoir but found that the correct tubing to the nozzle is smaller. Can anybody tell me what size it is supposed to be?

Do the autoparts shops carry this stuff?

I'm pretty sure I've seen it in the LMC catalogs, but I'd like to grab it locally if possible since I wasn't planning to put an order in with LMC for a while.

My hose measures .285" ID, and the fitting on the reservoir measures .300". Siri tells me that 9/32" is .2812". But she says that 7MM is .280".

I'd think any vacuum hose would work. I think.

Ok, I guess that's where I'm running into an issue Gary, the nipple on my reservoir is only 0.200". I cut my tubing back a half an inch to remove the flare and it appears to be 0.250-0.260" ID. I have a new washer fluid spray nozzle from LMC and it looks like it's made for 0.25" tubing.

The funny part is, the nipple on the INCORRECT reservoir I removed is 0.300"!

Bugger!

So what in the heck do I have for a reservoir now? This one was removed from the 1985 Bullnose that I junked. At least I think that's where it came from. I have another one here that I'm pretty sure I removed from a 1983.

Let's make sure we are talking about the same thing. The pic below is from Big Blue's windshield washer pump outlet.

But can you use smaller tubing and make it stretch over the spray nozzle's input?

Hi Gary, yes same fitting. You can even tell in the picture that the one on mine is smaller. Interesting.
Oh well, I guess I'll see if I can get some smaller tubing that will fit over the nozzle, or I'll get a reducer barb to go between the two sizes if I have to.

Another option would be to use a check-valve between the 2 hoses, like modern vehicles have. It's more-important if you drive uphill frequently (or extremely, as when off-roading), or if you accelerate hard. In either case, the fluid can run out the nozzles when the pump motor isn't running. The valve stops that.
